# ADR-0002: Attachment Zammad di QNAP OSS (Private Bucket)

**Status:** Accepted  
**Date:** 2026-07-02

---

## Context

Zammad menyimpan lampiran tiket. Opsi storage:

1. Disk lokal container/volume
2. S3-compatible object storage (QNAP QuObjects)
3. NFS share

QNAP OSS sudah dipakai untuk `super-apps` (avatar publik) di geonet-console.

---

## Decision

- Bucket: **`zammad-attachments`**
- Endpoint: `http://10.100.1.10:8010`
- **Private** — tanpa public ACL atau nginx proxy publik
- Credential: reuse access key format `super-apps:<key-id>` dari geonet-console `.env`
- Zammad config: Simple Storage (S3), `force_path_style: true`

---

## Consequences

**Positive**

- Attachment tidak memenuhi disk root LVM di .24
- Pola sama dengan stack existing (AWS SDK, QNAP)
- Backup NAS terpusat

**Negative**

- Ketergantungan jaringan internal ke QNAP
- QuObjects kadang `503` singkat setelah bucket baru — perlu retry
